Solve 3x2+7x+1=0 using the quadratic formula.

NNADVOKAT [17]

Answer:

$x=\frac{-7+-\sqrt{37} }{6}$

Step-by-step explanation:

This (±) goes between the $-7$ and $\sqrt{37}$

$3x^{2} +7x+1=0$

$ax^{2} +bx+c$

$-b$ ± $\sqrt{b^2-4ac}$ /2a

$-7$ ± $\sqrt{(7)^2-4(3)(1)}$ /2(3)

$-7$ ± $\sqrt{49-12}$ /6

$-7$ ± $\sqrt{37}/6$

Item 10 A 12-foot ladder leans against the side of a house with its base 3 feet from the house. Use the Pythagorean Theorem to a

Yanka [14]

Answer:

11.6 foot

Step-by-step explanation:

Length of the Ladder=12 foot

Distance of the base of the Ladder from the House=3 foot

Since the ladder leans against the wall in a slant position, it is the hypotenuse.

From Pythagoras Theorem,

Hypotenuse ²= Opposite ²+ Adjacent ²

12²=3²+x²

x²= 12²-3²=144-9=135

x=√135=11.61895003862

The Ladder reaches up to a height of 11.6 foot (to the nearest tenth) on the house.
